Bofors 40x311r

thingiverse

This is an exact replica of the Bofors 40mm L60 anti-aircraft cannon ammunition used by several nations during World War II. This model is specifically designed for the 40x311r version, which is distinct from the 40x364r variant used in the post-war L70 cannon, as well as the Sgt. York DIVAD. I consulted a few reference images to create this approximation, some of which presented slightly conflicting shapes and styles, but I am confident that my design closely resembles the original. Be warned: printing this model at 1:1 scale requires a large printer, as the case alone stands at an impressive 311mm tall. My test print on a CR-10 turned out well, but some minor adjustments to the tolerances may be necessary for the shell and case to fit together smoothly.
